Does sound like the slot, happens occasionally. Hey at least you're learning about PC's, put it down to experience. Good luck getting it sorted.
Cheers man! Even if it started working I would never be happy that it would be consistent!
Ill be returning it and Ill wait for the new NEXT GEN card I guess! Ill probably go with the Q9450 aswell!
Yet again, thanks allot, you found the problem in the end, infact, if I had explained it better you probably would have got it straight away lol
